IUDSON W. HAKES, OF MILLBURY, MASSACHUSETTS.

LOON-SHUTTLE.

Specification of Letters Patent.

Patented Mar. 27, 1917..

Application filed April 6, 1914. Serial No. 829,804.

1 0 all whom it may concern:

Be it known that 1', Hanson W. IIAKES, a citizen of the United States, residing at Miilbury, in the county of Forcester and State of Massachusetts, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to a loom shuttle and particularly to an improved handthreading eye adapted for use in such shuttles.

The principal object of my invention is to provide a hand-threading shuttle eye which can be cheaply and accurately manufactured and which will be extremely durable and reliable when in use.

With this object in view my invention consists essentially in certain improvements in shuttle eyes of the type shown in United States Patents Nos. 849,212 and 849,213, issued April 2, 1907. My invention further consists in certain devices and combinations in a hand-threading shuttle eye which will be hereinafter described and more specifically pointed out in the appended claim.

A preferred form of my invention is shown in the drawings in which- Figure l is a top plan view of a portion of a shuttle showing my improved threading eye in position therein;

Fig. 2 is a transverse sectional view taken along the line a-a in Fig. 1 and looking in the direction of the arrow 2; this figure also showing an additional feature embodied therein;

Fig. 3 is a transverse sectional view similar to Fig. 2 but looking in the direction of the arrow 3 in Fig. 1;

Fig. 4 is a side elevation of the portion of the shuttle shown in Fig. 1, drawn on an enlarged scale;

Fig. 5 is a longitudinal sectional view of the shuttle eye and Fig. 6 is a detail sectional view taken along the line 6-6 in Fig. 1.

I have shown my improved handthreading shuttle eye as mounted in a shuttle 10 of ordinary construction having a horizontal threading slot 11 (Fig. 4) communicating with the oblique upwardly extending slot 12. The slot 11 communicates at its rear end with a transverse cylindrical hole 13 within which is secured my improved eye 14. A cylindrical opening 15 is formed in the upper portion of the shuttle and communicates by a straight slot 16 with the bobbin holding recess 18 in the body of the shuttle. These various features of the shuttle body are of the usual construction and form no part of my invention except as to the specific form of the transverse cylindrical hole 13.

The threading eye 14 is formed of a straight cylindrical shell 19 having a longitudinal slot 20 extending from one end the eye is enlarged as shown at 22 and is provided with a screw thread upon its outer surface. In some instances I have found it desirable to form the enlarged end 22 with an inward taper so that the screw thread may more easily engage the body of the shuttle. A slot 23 in the end 22 provides means for inserting and removing the threading eye.

The transverse cylindrical passage 13 is formed in two diameters, the portion 24 shown at the left in Fig. 2 closely tting the shell 19, while the portion 25 shown at the right in said figure allows clearance around the outer surface of the shell so that the thread in passing down through the oblique slot 12 may readily pass through the slot 21 into the threading eye. A clearance space 26 (Fig. 6) is provided along one side of the cylindrical passage 24 so that the thread may pass from the horizontal slot 11 through the longitudinal slot 20 into the eye 14. This clearance space is conveniently formed by inserting a small 'rotating cutter into the enlarged passage 25 and causing the same to cut away one slde of the passage 24 to a point beyond the end of the eye 14. It is not necessary and is usually not desirable that this clearance space should extend entirely through the shuttle body.

In Figs. 2 3 and 4 I have shown an additional feature which may when desired be used in connection with the construction previously described. This feature consists in a cylindrical thimble 27 which is externally threaded and is provided with an inwardly extending flange 28. The inside diameter of this flange will preferably substantially coincide with the diameter of the hole in the eye 14. At one side the thimble 27 is provided with a longitudinal slot 29, and an additional slot 80 may be formed in the flange 28 opposite to the slot 29 so that the thimble may be easily inserted by the use of a screw driver. The slot 29 is positioned in substantial alinement with the horizontal threading slot 11 (Fig. 4) in the shuttle body, while the slot 20 in the shuttle eye is angularly displaced out of alinement with the slots 29 and 11, the usual angular qdisplacement being 90 as shown in Fig. 6.

This thimble When in position constitutes a contracted member spaced from the end of the eye 14 a distance just sufficient to afford clearance for the passage of the thread into the eye and is very effective to prevent the thread from thereafter escaping from the eye 14.

Having thus described my invention it will be evident that many changes can be made therein by one skilled in the art with; out departing from the spirit and scope of my invention and I do not Wish to be limited to the specific details herein described but 20 What I do claim is In a loom shuttle, in combination, a shuttle body having a hole extending transversely therethrough, a cylindrical hand-threading slotted shuttle eye supported in said hole,

and a cylindrical slotted thiinble mounted in.
